Water surface floating oil extraction device for municipal water conservancy project and use method of water surface floating oil extraction device

Abstract

The invention relates to the field of municipal water conservancy purification, in particular to a water surface floating oil extraction device for municipal water conservancy projects and a using method thereof. According to the water surface floating oil extracting device for the municipal water conservancy project, through cooperation of a fourth liquid level sensor and an electronic push rod, the height of an oil collecting ring can be flexibly adjusted along with the floating height of an annular floating barrel, the top face of the oil collecting ring is kept at the set height below the water surface height all the time, and floating oil on the surface layer of the water surface is accurately sucked; meanwhile, the oil collecting ring of an annular structure is wide in coverage and free of dead corners, floating oil on the periphery of the device can be rapidly sucked into the oil filtering cavity in cooperation with the telescopic hose, the extraction efficiency is high, large-size floating objects on the water surface can be preliminarily and effectively filtered through the arrangement of the filtering net cylinder, solid impurities of a water-oil mixture are filtered out through cooperation of the impurity filtering cylinder, and the oil filtering efficiency is high. And the filtering efficiency can be effectively improved through bidirectional filtering of the oil filtering cylinder and the water filtering cylinder.

Description

technical field [0001] The invention relates to the field of municipal water conservancy purification, in particular to a water surface oil slick extraction device for municipal water conservancy projects and a use method thereof. Background technique [0002] Oil slick pollution on water surface may come from three aspects: discharge of oily wastewater from ships, discharge of industrial oily wastewater, offshore oil exploitation; leakage and discharge of oily sewage from ships, platforms or factories, as well as occurrence of marine accidents, which cause oil pollution on the water surface. Pollution, oil slicks not only form an oil film on the water surface, destroying the circulation of oxygen; some dissolved oils can consume dissolved oxygen in the water body, causing hypoxia in the water body and the death of animals and plants in the water body, thus leading to the destruction of the ecological chain. [0003] There are the following problems in the prior art that hav...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for extracting slick oil on the water surface of municipal water conservancy projects and its use method, so as to solve the problem that the high speed of the suction port cannot be adjusted flexibly and the suction efficiency is low, and the floating objects on the water surface are easy to block. The device needs to be dredged and cleaned frequently and the oil storage is limited and the service life is short.
